What is the evidence for Salaam’s brain becoming more human, compared to a chimpanzee? How did scientistsget this information, since brains do not fossilize?
What will be an ideal response?
Answer: The evidence is that chimps by the age 3 already had full grown adult brains, however Salaam’s brain was not fully developed, it was only 75% fully grown, for us humans, we take over 2 decades to fully develop a mature brain meaning, something happened to Salaam’s brain and was starting to become more human since the brain wasn’t fully developed and was taking much more longer to develop. They got this information by comparing it to other fossils to know how big salaam’s brain should’ve been as an adult. They had a cast of the brain case called an endocast which preserves the impressions of the brains surface. Evidence also shows that the lunate sulcus which is found posterior of the brain is found in chimps, but not found in human brains,the reason is they believe the lunate sulcus was moved back more to create a bigger neo cortex, the thinking part of the brain
